--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
E.g. -fcall-saved-rdi option is ABI changing option, so you'd need to have
everything (from libc, libgcov, libgcc, libstdc++, ...) built that way. 
Furthermore, I don't think we consider this case e.g. to disallow tail call
optimization (which is generally not possible under such weird ABI).
